I contain DNA and direct the cell's activities.
Nucleus
I am the rigid outer layer that supports and protects plant cells.
Cell Wall
What energy source powers photosynthesis?
Sunlight
What sugar do plants make during photosynthesis?
Glucose
Are plant cells or animal cells the only ones with mitochondria?
Neither! Both plant and animal cells have mitochondria.
I make proteins for the cell.
Ribosomes
I store water and help keep a plant cell firm.
Central vacuole
What organelle carries out photosynthesis?
Chloroplast
What molecule provides usable energy for cell activities?
ATP
Name three organelles found in both plant and animal cells.
Examples: nucleus, mitochondria, ribosomes, cell membrane, ER, Golgi apparatus.
I control what enters and leaves the cell.
Cell Membrane
I contain chlorophyll and carry out photosynthesis.
Chloroplast
What are the three inputs needed for photosynthesis?
Sunlight, water, and carbon dioxide
Which organelle produces most of the cell's ATP?
Mitochondria
Why do plant cells need chloroplasts if they already have mitochondria?
Chloroplasts make glucose using sunlight; mitochondria help release energy from glucose to make ATP.
I modify, sort, and package proteins.
Golgi Apparatus
Name two structures found in plant cells but not typical animal cells.
Cell wall and chloroplasts
What sugar and gas are produced during photosynthesis?
Glucose and Oxygen
What two substances are used during cellular respiration?
Glucose and oxygen
A plant cell's central vacuole loses a lot of water. What might happen?
The cell loses firmness and the plant may wilt.
I help make and transport proteins or lipids throughout the cell.
Endoplasmic Reticulum
Why do plant cells need both a cell wall and a cell membrane?
The cell wall provides support and protection; the cell membrane regulates what enters and leaves.
What happens to photosynthesis when a plant receives no light?
Photosynthesis stops without light, so the plant cannot make new glucose through that process.
Explain the difference between glucose and ATP.
Glucose stores chemical energy; ATP supplies usable energy directly for cell activities.
Explain how sunlight can eventually help a plant cell make ATP.
Chloroplasts use sunlight to make glucose. Mitochondria use glucose and oxygen during cellular respiration to produce ATP.
